Amsoil Product Data Bulletin

Reduces Friction, Heat and Wear

In high heat conditions, AMSOIL Synthetic Metric Motorcycle Oil exceeds the standard for high-temperature film strength to deliver excellent wear protection. It keeps engines running cool by effectively reducing friction and heat, and it contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions. AMSOIL Synthetic Metric Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation-inhibitor additives. It is extremely resistant to volatility and is engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.

Smooth, Confident Shifts

AMSOIL Synthetic Metric Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. It is engineered to control heat and prevent slippage and glazing, promoting longer clutch life.

Controls Foam

High-rpm operation causes some motor oils to foam. When foam bubbles travel between gear teeth or engine components, they collapse, allowing metal surfaces to contact, causing wear. AMSOIL Synthetic Metric Motorcycle Oil contains advanced anti-foam additives that help prevent foam, allowing riders to confidently push their bikes to the limit.


  • Premium wear protection
  • Smooth, confident shifts
  • Cool, clean performance



Delivers Superior Rust and Corrosion protection

Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage, such as uncontrolled wear, compression loss and blow-by. Good rust protection, however, comes by design and is not natural to motor oils. Unlike many motorcycle oils, AMSOIL Synthetic Metric Motorcycle Oil contains special anti-rust agents that deliver superior rust protection. With its high 11.1 total base number (TBN), AMSOIL Synthetic Metric Motorcycle Oil provides greater protection from acid corrosion and helps maintain internal engine cleanliness.


AMSOIL 10W-30 Synthetic Metric Motorcycle Oil is engineered for motorcycles that require 10W-30 motorcycle oil, including those made by Honda, Yamaha, Kawasaki and Suzuki.* Recommended for transmissions requiring an API GL-1 fluid. Not recommended where an API GL-4 or GL-5 gear oil is required. GL-1 • API SG, SL/CF • JASO MA/MA2


Recommended for use up to twice the motorcycle manufacturer-recommended change interval (miles/hours) or one year, whichever comes first, in engines and transmissions. When using an oil filter other than AMSOIL Ea® Motorcycle Oil Filter, change the filter at standard intervals. Racing or modified engines are excluded from extended drain interval recommendations; oil changes are at the owner’s discretion.

First time

By  FRANK,  a  Verified Buyer  from  NJ  on  January 01, 2022

I just picked this bike up a Kawasaki concours 2016. This is my first oil change with amsoil and already I hear the motor running quieter! To me. That’s win-win. Win-win! I will definitely keep using this. I use it in my side-by-side and my Harley. I will be using this in my cars also. I am a preferred customer and enjoy the savings.
Difficult to find on the road like all motorcycle specific

By  CHUCK,  a  Verified Buyer  from  Daytona Fl.  on  December 27, 2021

Gave it four stars only because of its availability on the road . And would not know about engine wear with out tearing down the motor . haven’t had to do that on any of the motorcycles I have owned . I did have main bearing failure on a 4.3 GMC Safari van that I owned from new at 98,700 mi. I did all the oil changes using NAPA WIX filters my self around the 5,000 mile mark using Amsoil . That is the only engine failure I have had in my life of 64 years of vehicle ownership. Now I only use Amsoil in my chain saws and motorcycle. I consider them being more extreme use and worth the added cost.
Hint: Motorcycle shops – if you stocked AMSOIL you could drop all the others as there would be no reason for them!
I’m just glad I could afford it.

By  WILLIAM,  a  Verified Buyer  from  Arizona  on  November 29, 2021

I didn’t ever think I’d be able to afford Amsoil, however, with the price of oil going up all over the place, is not that much different. So now I can finally afford Amsoil, yeah me.
The only one

By  DOUG,  a  Verified Buyer  from  Pismo Beach CA  on  October 19, 2021

Over 100K on the 2007 1250 Bandit, I believe from the use of Metric 10W-40. I’ve used all the available synthetics for motorcycles on the Bandit but the only oil that’ll let me go as long as I want to between oil changes is this oil. Every other oil that included all the lauded brands had to be changed between 1500 to 2000 miles because of the Bandits shifting becoming “clunky”. The very first change into the Metric made a believer out of me by the obvious fact my shifting never gets hard with this product. I change my oil now at 4000 miles “just because” with nothing telling me to, like a “clunky” shift.

Amsoil 10/30 metric works great
By Curveman 8/29/2016

from Manchester Ct.

I have found that my bikes run and shift great with Amsoil metric. I have a Honda CB1100 and a Honda Gl 1800. I will buy it again.

Bottom Line
Yes, I would recommend this to a friend

I believe in Amsoil!

You know how hot it gets in Florida especially when the motor is cooking on main st in Daytona. Amsoil significantly reduced how hot the motor gets and eliminated a ton of valvetrain noise. Simply put, I run Amsoil in all my bikes and vehicles.

Best motorcycle oil

I had been using Mobil 1 in my Valkyrie. During a trip from Denver to Tucson on a Memorial Day weekend I noticed clunky shifting when I got to Tucson. The temp was pushing 100 and we encountered some stop and go traffic. The tranny was definitely shifting hard. It seemed that the oil had broken down more than normal. That summer I was at a goldwing rally and stopped at the Amsoil booth to talk with a representative. I told him about the hard shifting. He told me that Mobile 1 had reduced the amount of silicates in their synthetics. He told me to try the 10W-40 Metric. He said I would notice a difference. He’s the rep, he has to say that. However, I had heard good things about Amsoil from some other riders so decided to give it a try. What an unbelievable difference. Just shifting into 1st (which there is usually a clunk) and driving out of my neighborhood the shifting was smoother than it ever had been. I gave that oil change 5000 miles. Our trip that summer was the remainder of Route 66 from Amarillo to Santa Monica. Going thru Needles it was 106. Never did the shifting get hard or cluncky. My Valkyrie has 108,000 miles and I also bought an 05 Wing which shifts smooth as silk. Best oil ever!!

The air cooled bike stays cool.

Switching from conventional I notice that the running temperature of my XR600 is about 20 degrees cooler and the valvetrain is much quieter.

Something new with use.

Routinely changing the oil on my Gsx-s750 brings with it a new appreciation for Amsoil oil. I’m on my 3rd oil change on this bike and I swear the oil maintains its clarity further and further into each new oil change. Currently approximately 2200 miles into my last change and the oil is still clear in the viewing window. Its a little darker in color like an IPA but still clear. Clarity has to be associated with cleanliness, and therefor my engine must be very clean. One happy camper.

Love my Honda

I have over 60,000 miles on my 1993 Honda CBR1000F. Before using Amsoil, valve adjustments were an annual ritual. Since switching to Amsoil at 25,000 miles valve adjustments are few and far between. Oil consumption is low and gas mileage is up 5-10%.
